Theoretical concepts should be represented in both side of theoretical. As I read the theoretical, there are presented about only the negative side of Groupthink even though there are some positive of the theory. The writer should present both side and let the reader analyze the theory by themselves. For example,there are also may routine occasions when a groupthink mode is actually helpful because it makes for a speedy and amicable consensus on issue of minor importance.I claim that the positive side are concept that need to be re-examined.
